There seems to be a lot of money there but the problem relative to Europe is China is a difficult place to live as a foreigner. It's not like moving to Madrid, Milan, Munich etc. Top footballers like to live glamorous lifestyles in European cities. Going to USA would be attractive if they were throwing the same kind of money around as the Chinese are, but China is not the same and many footballers will struggle to fit in.
I'm sure they will sign a lot of fairly well known players but will they be in for the likes of Messi, Ronaldo, Bale, Neymar etc?
